Shading sign of endometrioma

Case contributed by Dr Prashant Gupta

Presentation

Menstrual disturbance for one month.

Patient Data

Age: 50 years
Gender: Female
MRI

T1 hyperintense cyst in the right ovary. T1 fat saturation showing that the hyperintensity is not fat but hemorrhage. T2 shading sign. In the sagittal plane, there is a large left ovarian cyst as well. A tortuous tubular hyperintensity is seen in the right adnexa, likely a hematosalpinx.

Case Discussion

Shading sign is the magnetic resonance (MR) imaging finding of T2 shortening in an adnexal cyst that is hyperintense on T1-weighted images. It is helpful as a distinguishing feature of endometriotic cysts (endometriomas) on MR imaging.
